Lone Pine (Stephen Mandel): The 'Tiger Cub' hedge fund held 805,269 shares of Apple at the end of Q3. Lone Pine sold 617,940 shares of Apple during the third-quarter.

Third Point LLC (Daniel Loeb): Third point owned 710,000 shares of Apple or a 0.8% stake as of 9/30/2012. Third Point had added 285,000 shares of Apple during Q3.

In his Q4 letter to investors yesterday, Einhorn wrote how their "bruised" Apple stake hurt their fourth quarter performance. The fund was down 4.9% in Q4.

Einhorn also said that with Apple shares sliding in fourth quarter they erased their gains from the third quarter. However, he said he used that opportunity to repurchase shares they sold in the third quarter.

Also, as a reminder, hedge funds only have to disclose their long holdings in 13F filings with the SEC. Fourth quarter 13Fs will be out in mid-February.
